BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 709,161, dated September 16, 1902'.

Application filed January 16, 1902. Serial No. 90,022. (No model.)

To all ZU7'L0777/ it may concern:

Be it known that I, IGNATZ KosoHERAK, a citizen of the United States, residing in New York, borough of Richmond,and State of New York, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

This invention relates to certain improvements in bottle'stoppers of that class which are designed to be used for carbonated beverages and in which the well-known lightning bottle-stopper is used for closing the bottle after the same is filled, but having its head detachable from the bail or yoke, so as to permit the ready closing of the bottle after it is filled and having means for retaining the bottle-stopper on the bottle-head, so as to prevent its accidental disengagement from the yoke; and the invention consists of a bottle-stopper which comprises a bail or yoke,

a lever pivoted to the neck-band of the bottle and provided with eyes for engaging the .inwardly-bent ends of the bail, a stopper the head of which is provided with a recess having a transverse groove at the inner end thereof for detaching the head of the stopper from the bail, and a sheet-metal cap having recesses at diametrically opposite points, so that the cap can be fitted securely over the head of the stopper, so as to retain the bail or yoke in proper relation with the head when the bottle is closed.

In the accompanying drawings, Figure 1 is a side elevation of my improved bottle-stopper. Fig. 2 is a vertical central section of the same. Fig. 3 is a side elevation of the stopper with the bail-retaining cap removed therefrom; and Figs. 4 and 5 are perspective views, respectively,of the bottle-head and the sheet-metal cap for the same.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the neck of a bottle for carbonated beverages, and B the usual wire neck-band for the same.

0 is a U-shaped lever which is pivoted at diametrically opposite points of the wire neck-band and provided with eyes into which are sprung the inwardly-bent ends of a closing bail or yoke I) of inverted-U shape.

D is the stopper, which is provided with a shank for attaching the rubber packing E,

which is interposed between the head and mouth of the bottle for tightly closing the same. The head D of the stopperD is made of approximately cylindrical shape and. provided with a recess 6, the upper edge of which is inclined, terminating in a central transverse groove e, into which the bail or yoke 11 is placed when the stopper is applied in closed position to the bottle.

The bottle is filled in a filling-machine hav ing a charginghead as usually employed in machines for bottling carbonated beverages, the stopper being placed on the bottle-mouth as soon as the bottle is filled and the yoke then introduced into the recess and central groove of the head, after which the lever is depressed into closed position, as shown in Fig. 3, thereby holding the stopper firmly in position on the bottle.

When the bottles are closed, a cap F, made of cylindrical shape, with a filletf at its upper end and diametrical recesses f extending upwardly from its lower edge, is adapted to be sprung or forced over the head of the stopper, so that the recesses fit over the upper part of the bail, as shown in Fig. 1. The friction of the cylindrical portion of the cap F holds the cap firmly in position on the stopper-head, so that the bail cannot become detached accidentally from the stopper, and the friction must be sufficient that the cap cannot be removed by the fingers. When the cap is thus placed in position, it permits the opening and closing of the stopper without allowing the stopper-head to become detached from the bail or yoke, the cap forming a connecting device for this purpose. When the empty bottles are to be refilled, the caps are quickly removed by a suitable hand-tool or by other means which is adapted to engage the fillet and remove the cap from the stopper-head, so that the latter can then be detached from the bail or yoke, so as to permit the refilling of the bottle and replacing of the stopper in position thereon and the relocking of the stopper by the action of the bail or yoke and pivoted lever, as before described. When the bottle is filled and'ready for being shipped, the cap is again replaced thereon, the cap and stopper-head being separate be fore the bottles are filled, so as to be handy for being replaced on the bottle.

My improved bottle-stopper is a very convenient and effective stopper for carbonated beverages, so as to permit the application of the well-known lightning bottle-stopper to bottles containing beverages charged with carbonic acid. As the sheet-metal caps are made from the same dies each one can be placed indiscriminately on any stopper-head when the bottles are ready for being shipped, thereby closing up the recessed portion of the stopper-head, so as to prevent the detaching of the same from the bail or yoke.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a bottle-neck provided with a Wire neck-band, of a U-shaped lever, a bail or yoke, a stopper the head of which is provided With a recess and a transverse groove in the inner end of said recess, and a sheet-metal cap fitting over the head of the stopper and provided with recesses at diametrically opposite points for the bail or yoke, substantially as set forth.

2. The combination, with a bottle-neck provided with a Wire neck-band, of a U-shaped lever, a bail or yoke, a stopper having its head provided with a recess extending inwardly from one side and terminating in a diametrical groove, and a sheet-metal cap fitting over said head and provided with a fillet at its upper edge and upwardly-extending recesses at diametrically opposite points, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in pres ence of two subscribing Witnesses.

IGNATZ KOSCHERAK.
